What Do Increasing Tsh Levels Mean
My TSH level was 6.2 and now it's 3.4 after increasing my thyroid medicine. What does this mean? What is a normal range?
My TSH levels are 0.344. What does this mean and are there any symptoms associated with these levels?
1 of 3 things: Hi. If your TSH is 0.344, which is just slightly below the normal range, it could be: 1) normal, no thyroid disease (the "normal range EXCLUDES 5% of normal values), 2) mildly "hot" (autonomously hyperfunctioning) nodule(s), or 3) your doctor checked it while it was heading down.

Normal: Hi. At face value and in the vast majority of cases, that TSH represents normal thyroid fountain; the one exception would be pituitary disease.

More workup: Currently, it points to hyperthyroidism but you need to complete the work up to know for sure. At the very least, i would repeat the TSH along with the free hormones T4 and t3 (liothyronine). If they also point to hyperthyroidism, then proceed further to find the exact cause for this. Tsh alone does not give you a complete picture. ...Read more
